Legacy Controllers
Legacy controllers are based on PrestaShop’s custom framework and go a long way back. All front controllers and all Admin controllers that haven’t been migrated to Symfony yet are based on this.
Execution flow
Legacy controllers work best when a Controller performs a single action, for example, render a page. The process has been divided in several methods, which simplifies customization via method override.
